Could use some help with joysticks . . .
 
Posted by Dan at 1/24/2001 9:51 PM EST


Student on team #112, Gear Grinders, from Buffalo Grove HS and Motorola.



As a team, we have had problems with the joysticks for the past 2 years (since we've existed :)). They keep wanting to 're-calibrate' themselves, i.e. the center, and extreme values vary from use to use. To combat this effect we have tried duct tape on the trims and adding buffer regions in software for a 'neutral zone' in the center of the joysticks' axes. Can any other veteran teams give us a hand in telling us a better method for this?

I can speak as a veteran member of the Truck Town Terror (#68) team, there is no good way that we have found. We run into the same problem amost every time we run our robot.

The joysticks used for R/C model airplanes don't seem to have neutral/drifting problems but I suspect they are LOTS more expensive... People who play lots of computer games should be able to provide some input about their favorite joysticks.

Try replacing the potentiometer with a proper value resistor. It will always give you the same resistance.
